To all whom it may concern: Y

Beit known that I, FRED KILLEFER, a citizen of the United States,residing at Los Angeles, California, have invented certain new anduseful Improvements in Forging- Presses, of which the following is aspeciication.

My invention relates to improvements in forging presses and t-he objectof the invention is to provide a press of this character which whilecapable of exerting great pressure upon the blank or article to betreated, will yet be capable of quick and ready adjustment toaccommodate itself to a large variety of work. It is desirable indevices of this character to use toggle joints as the means for applyingthe necessary pressure as by this means a very powerful pressure may beexerted by very simple mechanism, but in the use of toggle joints as themeans for applying the necessary power to the forging head, only alimited movement of the head can be secured consistent with the maximumamount of power to be derived from the toggle joint, and consequentlyunder ordinary conditions the press could only handle work of verylimited range of thickness. There are mechanical object-ions againstadjusting the anvil.

It is the object of the present invention, therefore, to provide meansby which the forging head may be quickly and easily adjusted withoutdisturbing the operating toggles, the adjustment being made at will toaccommodate the press to work of greater varying thickness.

The invention includes the novel features of construction andarrangement and combination of parts hereinafter described, andparticularly set forth in the appended claims.

It is illustrated in the accompanying drawings, in which Figure l is aside elevation. Fig. 2 a front view, and Fig. 3 is a transversesectional view on line 3 3 Fig. 2.

Referring by reference characters to this drawing', the numeral ldesignates the anvil and 2 the forging head, the latter being guided byguides 3 carried by standards 4, which tie the anvil to an upper crossmember 5.

6 represents the toggle links which are connected at the top to thecross member 5 Aand at the bottom to the bearing member 7 and it will beunderstood that the toggle members are operated by the usual operatingmechanism 6a, not necessary to be particularly described herein.

For connecting the bearing member 7 and forging head, I provide a screw8 having one end rotatably connected with one of these members and itsother end threaded into the other member. I preferably rotatably connectthe head of the screw with the bearing member at the bottom of thetoggle joint by any suitable rotatable connection and screw its lowerend into a correspondingly threaded opening in the forging head, itbeing understood of course that the screw is made of a size and strengthcommensurate with the force which is to be applied. The screw carries apulley 9 which may be secured thereto or formed rigidly therewith.Around this pulley passes an endless belt or band l0 which extendshorizontally to the side of the apparatus where it passes over idlepulleys 1l and thence vertically downward to a pulley l2 journaled upona suitable shaft and provided with a hand wheel or crank or other meansfor rotating the same. It will be seen that by the rotation of the handwheel in the proper direction, the screw will be turned and the headquickly raised or lowered, while at the same time not interfering in anyway with the toggle action or forging movement o-f the head Vas themovement of the head under the action of the toggles is so slight as notto interfere with the belt connections described.

Coil springs 13 are provided on each side of the toggle arms 6 to assistin returning the forging head 2 to its raised position. They are securedat their lower ends to the forging head by suitable eye-bolts 14 and attheir upper ends to the cross piece 5 by the eye-bolts 15.

Having thus described my invention, what I claim is l. In a forgingpress, a stationary anvil, a vertically moving forging head, operatingmeans for the forging head, a screw con necting said forging head andoperating means, and flexible connections extending to the side of thepress for operating the screw.

2. In a forging press, a stationary anvil, a vertically moving forginghead, toggle mechanism for opera-ting the same, a screw connecting saidhead and toggle operating In testimony whereof, I aflix my signaturemeolmnism, i pulley fast on the screw, a pulin presence of twoWitnesses.
